Dear Thermal Spray Community, Would anyone have advice or studies to share that may relate non-destructive characterization of thermally sprayed coatings to the coating bonding strength ? From my current experience, it seems that non-destructive techniques like ultrasounds (UT) may give a degree of "pass/fail" information, but it doesn't seem possible to relate/assess if the coating may perform as desired, without having conducting extensive mechanical testing.Thanks in advance for any suggestions you may be able to provide !
Hi Paul, Thank you for very much for your insights here, I appreciate the in-depth perspective you provide to the question. I guess it goes back to really defining the question of "What is desired of this system ?" and then only "How do I assess it is performing as expected ? What are the requirements to confirm performance ?". It's interesting as on the academic research side we tend to spend a lot of time pondering a- through f-, and while this is natural to some extent, defining g- is the most important for achieving any form of application. I will definitely keep this in mind in my future considerations.
